IMPROVEMENT IN TURBINATE FORCE-PUMP.

Speciijcation forming part of Letters Patent N0. 55,082, dated May 29, 1866.

To all whom it may concern:

Be it known that I, JOHN HARTMAN AU-A GUST GERIGKE, ot' New Orleans, in the parish of Orleans and State of Louisiana, have invented a new and useful Improvement in Force-Pumps; and 1 do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference heilig had to the accompanying drawings, forming part of this specification, in which- Figure l is a vertical section of a pump made according to my invention 0n the line w of Fig. 4L. Fig. 2 is an under-side view of the rotating turbinate wheel A. Fig. 3 is a section ot' said turbinate wheel on the line y of Fig. 2. Fig. et is a bottom view ofthe centripetal chamber H, taken on the line x of Fig. 1, from beneath the bottom plate, M. Fig. 5 is a top view of said chamber H, taken from the line z of Fig. l.

Similar letters ot' reference indicate like parts.

This invention consists in a force-pump operating on the principle of a turbine wheel, anddesigned for raising great bodies of water in short periods ot' time, as when draining low lands, pumping water out of ships and out of mines and other low places.

A designates a turbinate wheel consisting ot' a hollow truncated cone inverted, with vanes or paddles D, E, and F. lThe wheel is fastened upon the vertical shaft B, whose foot or point O is stepped in a pillow-block, P, on which it turns. The foot or point O is made removable, as 1s also the block P, and they will be oiled from a small pipe, (not shown,) The top of the shaft B is properly connected to the upper side of the discharge-pipe C, so as to be capable of longitudinal motion through it as well as rotary motion, by which means the length of the discharge-pipe may bechanged without disturbing the working parts ot the pump. The vane ofthe bevel wheel or pulley R is lengthened out below, so as to turn in a pillow-block or bearing, Q, fixed on the top of the pipe C. The vanes or paddles on the turbinate wheel are made in three systemsthat is to say, three of them, D, extend from its circumference quite to the apex or end of the wheel j, three ofthem extend from the circumference about two-thirds the length ot' the wheel, and the remaining three extend from the circumference about half its length.'

Vmove it outward toward the circumference of the wheel. Next after them the paddles E, and then the paddles F, take the water and elevate it by driving it against the sides ofthe i-nclosing-case G, whose'lower side should be submerged in the water. That portion of the water which runs over the edges ot' the vanes D is encountered by the vanes E and Fin succession, and receives a new impulse from each toward the space V at the top of the case G. The base ofthe case G has six openings, N, more or less, in its periphery, through which to admit the water to the turbinate wheel, and it rests on a bed-plate which has a circular cellar that receives the pillow-block P. This part of the case has straight sides, but it begins to be curved at the line of the top ot' the opening N, and runs thence upward and outward at a uniform distance from the edges ofthe vanes to the height of the wheel, where a rim is formed on it which receives the rim of an upper case, H, of similar Vform, set conversely to the case G. The lower part ot' the ease, about its openings, is surrounded by a paling' of wire-gauze or its equivalent, for the purpose of excluding the access to the vanes of solid and foreign substances, which might injure them. The case H rests on a plate, M, fixed to it, and which surrounds the shaft B with its l1 ub c. The circumference of the plate is about coincident with that ot' the highest part of the turbinate wheel, so that its periphery does not extendinto the annular space V. The case H is provided with xed vanes of the like general character as the vanes of the turbinate wheel. The long` vanes I extend from the hub a ofthe bottom of the ease to the side of the case H, the other vanes, K and L, being shorter, not extending to the hub, but distant therefrom by varying degrees, and yet being joined to the sides 0f said case H. These vanes, therefore, I, K, and L, severally project over the annular space V and divide the stream of Water which rises through it into an equal number of branches, which are delected by them toward the center of the case, as indicated by the arrows, While they proceed through the cells made by said vanes. The rotary motion imparted to the Water by the turbinate Wheel is gradually lost as it proceeds toward the center of the case H, and it becomes quiet and motionless therein, While it is gradually lifted by the pressure of the currents from below into the discharge-pipe C. The provision of the xed bottom M of the case H keeps the weight of the Water olf from the turbinate wheel, as well as the friction of the water after it has passed through the annular space V.

It will be observed of the operation of my pump that the Water will be seized by the paddlesof the quick tnrbinate wheel, and by virtue ofthe centiifugal force exerted, the water will mount obliquely to the case H and he thrown into the cells thereof, along whose Wal1s--thatis, the Yanes I, K, and L-it will run toward the center of the case. The curves of these Yanes, as Well as of thevanes D, E, and

F, are to be those of least resistance, so that the least friction possible will be produced in those operations.

All the parts of the pump may be of castron, except the shaft B, which should be of Wrought-iron.

I claim as new and desire to secure by Letters Patent- 1-. A turbnate Wheel inclosed, as shown, with three systems of vanes or paddles D E F, substantially as described.

2. The fixed case H over the turbinate wheel or engine which drives the water upward, fitted with three different systems of curved Yanes to direct the Water toward the center of the said case, substantially as described.

3. Separating the column of water in the case H and above it from the turbinate Wheel above-described by means ot' a Xed plate, M, substantially as described.
